Weierstrass型椭圆曲线上的扭点

Torsion Points on Elliptic Curves in Weierstrass Form

Philipp Habegger

摘要:

证明了在由$y^2=x^3+ax+b$定义的Weierstrass形式的椭圆曲线上,只有2个复数$a$和$b$与$4a^3+27b^2\not=0$满足$(1,*),(2,*),$和$(3,*)$三点同时挠.这对Masser和Zannier提出的一个问题给出了肯定的回答。因此,我们证实了一个特殊的情况下,在二维的相对Manin-Mumford猜想制定的粉红色和Masser-Zannier。

英文摘要:

We prove that there are only finitely many complex numbers $a$ and $b$ with $4a^3+27b^2\not=0$ such that the three points $(1,*),(2,*),$ and $(3,*)$ are simultaneously torsion on the elliptic curve defined in Weierstrass form by $y^2=x^3+ax+b$. This gives an affirmative answer to a question raised by Masser and Zannier. We thus confirm a special case in two dimensions of the relative Manin-Mumford Conjecture formulated by Pink and Masser-Zannier.
